So I finally found a listing of these on eCrater that specifically listed that they came with the boxes and everything else. I'm a bit skint this month, but I figured that I'm not going to get another chance anytime soon to finally get these.

They messaged me after I bought them, saying they don't have boxes or trading cards and offered either a discount or a refund. I went with the refund because them being complete was specifically the reason I bought from this vendor.
